BT Pro box shows not returned

[Walan]

I sent back my BT Pro box to BT as I cancelled EE TV.  The post office tracker shows it was delivered on the 19th March. I've got the proof of postage, I didn't sent if back in the white bag but the original box with the BT pre postage label printed on at the post office. Which is the best way to contact BT to sort this? It still says due back on the 16th May, thank you for any help.

Thanks for coming back to let us know it was sorted @Walan.

Can you just let us know what you did to get it sorted, just in case anyone else in the same position comes across your post?

I went on to live chat online and gave my proof of postage tracking number.  They saw the box was returned and updated my account to show returned and avoid a bill.
